“…The higher transmittance in SR grown GPI shows that the defect concentration in the grown crystal is less. The improvement of optical transparency of SR method grown TGS, KAP, ADP, KDP, DGZC, SA crystals has been reported [8,23,[26][27][28].…”

“…In the SR method as there are no such growth fluctuations or nonuniform growth rates the dislocations of the above causes are avoided. The low EPD in SR-grown TGS, KAP crystals has been already reported [7,10].…”

“…But in SR method the multi-faceted growth is avoided, so the growth sector boundaries are absent and hence the dislocations of the above causes are avoided. The enhancement of crystalline perfection, laser damage threshold, microhardness and optical transparency of the SR-grown benzophenone, TGS, KDP, benzimidazole, KAP crystal has been already reported [4][5][6][7][8][9][10].…”

“…Vicker's microhardness Analysis:-The significant property of any device material is its mechanical strength depicted by its hardness and the hardness of a material is a measure of its resistance to plastic deformation [19]. Practically, hardness is the resistance offered by a material to localized plastic deformation caused by scratching or by indentation [20].The permanent deformation can be achieved by indentation, bending, scratching or cutting [21].…”

Undoped and 0.5 mol% of L-aspartic acid (LA-C 4 H 7 NO 4 ) and L-threonine (LT-C 4 H 9 NO 3 ) doped sodium acid phthalate (NaAP) single crystals were successfully grown from aqueous solution by slow evaporation solution growth technique. Single X-ray diffraction revealed that the grown crystals possess orthorhombic crystal structure and revealed lattice distortion due to impurities. The crystallinity nature of the grown crystals was analyzed by powder X-ray diffraction analysis. Functional groups and the modes of vibrations were identified by FT-IR spectral analysis. Optical transmittance shows that L-threonine doped NaAP crystal possesses higher transparency compared to undoped NaAP and L-aspartic acid doped NaAP and the band gap energy values of the grown crystals were calculated. The photoluminescence properties of the grown crystals were investigated. The mechanical strength of the grown crystals was estimated by microhardness studies. The second harmonic generation of the grown crystals was confirmed by the Kurtz and Perry technique. Antibacterial activity of the title compounds against Streptococcus pneumoniae, Escherichia coli, and Klebsiella pneumonia strains was studied.Copy Right, IJAR, 2017,.

Introduction:-Semiorganic crystals are a new category of materials recently examined for their fascinating properties and stable physiochemical properties, which are significant for device fabrication and applied research [1,2]. The high nonlinearity, high resistance to laser-induced damage, low angular sensitivity and better mechanical hardness of semiorganic crystals incorporate in the strong NLO properties and chemical flexibility of organic materials with the physical sturdiness and excellent transmittance of inorganic materials [3][4][5][6]. In addition, the approach of high NLO efficiency organic molecules with the favorable physical properties of the inorganic materials has been an active area of research in the last two decades.Organic material with high nonlinear optical coefficients combines with an inorganic material exhibiting excellent physical properties, giving semiorganic material. Hydrogen bonding of acid based interaction between organic cation and an inorganic anion of semiorganic give mechanical strong and thermally stable NLO crystals [7]. Highly
